Rebar ndi dzina lodziwika bwino lazitsulo zachitsulo zopindika.Gawo lazitsulo zachitsulo zotentha zotentha zimakhala ndi HRB komanso zokolola zochepa za girediyo.H, R, ndi B ndi zilembo zoyambirira za mawu atatuwa, Hotrolled, Ribbed, and Bars, motsatana.
The otentha adagulung'undisa nthiti zitsulo bala amagawidwa m'magulu atatu: HRB335 (kalasi yakale ndi 20MnSi), kalasi yachitatu HRB400 (kalasi yakale ndi 20MnSiV, 20MnSiNb, 20Mnti), ndi kalasi zinayi HRB500.
Pali njira ziwiri zomwe zimagwiritsidwa ntchito nthawi zambiri zopangira rebar: imodzi ndiyo kuyika mawonekedwe a geometric, ndikuyika kapena kugawa molingana ndi mawonekedwe apakati a nthiti yopingasa ndi katayanidwe ka nthiti.Mtundu II.Kugawika kumeneku kumawonetsa kwambiri magwiridwe antchito a rebar.Yachiwiri imachokera pamagulu a machitidwe (kalasi), monga momwe dziko langa likugwiritsidwira ntchito panopa, rebar ndi (GB1499.2-2007) waya ndodo ndi 1499.1-2008), malinga ndi msinkhu wa mphamvu (zokolola zokolola / mphamvu zowonongeka) The rebar amagawidwa m'magulu 3;mu Japanese Industrial Standard (JI SG3112), rebar imagawidwa m'mitundu 5 malinga ndi magwiridwe antchito;mu British Standard (BS4461), magiredi angapo a mayeso a rebar amatchulidwanso.Kuphatikiza apo, ma rebars amathanso kugawidwa malinga ndi momwe amagwiritsidwira ntchito, monga zitsulo wamba za konkire yolimbitsa ndi zitsulo zotenthetsera kutentha kwa konkire yokhazikika.
Rebar ndi nthiti yachitsulo pamwamba, yomwe imadziwikanso kuti ribbed steel bar, nthawi zambiri imakhala ndi nthiti zautali wa 2 ndi nthiti zopingasa zomwe zimagawidwa molingana ndi kutalika kwake.Maonekedwe a nthiti yodutsa ndi ozungulira, herringbone ndi mawonekedwe a crescent.Amawonetsedwa mu millimeters ya awiri mwadzina.Kuzungulira mwadzina kwa kampando kokhala ndi nthiti kumafanana ndi m'mimba mwake mwamwambo wozungulira wagawo lofanana.M'mimba mwake mwadzina la rebar ndi 8-50 mm, ndipo ma diameter ovomerezeka ndi 8, 12, 16, 20, 25, 32, ndi 40 mm.Mipiringidzo yachitsulo yokhala ndi nthiti nthawi zambiri imakhala ndi kupsinjika kwa konkriti.Chifukwa cha zochita za nthiti, mipiringidzo yachitsulo yokhala ndi nthiti imakhala ndi luso lolumikizana kwambiri ndi konkriti, kotero imatha kupirira mphamvu zakunja.Mipiringidzo yachitsulo ya Ribbed imagwiritsidwa ntchito kwambiri muzomangamanga zosiyanasiyana, makamaka zazikulu, zolemetsa, zopepuka zokhala ndi mipanda yopyapyala komanso yokwera kwambiri.
Rebar amapangidwa ndi mphero zazing'ono.Mitundu ikuluikulu ya mphero zazing'ono zogubuduza ndi: zopitirira, zopitirira ndi mzere.Ambiri mwa mphero zing'onozing'ono zatsopano ndi zomwe zikugwiritsidwa ntchito padziko lonse lapansi ndizopitirirabe.Mphero zodziwika bwino za rebar ndi mphero zanthawi zonse zothamanga kwambiri komanso mphero za 4-slice high-production rebar.
Billet yomwe imagwiritsidwa ntchito pamphero yaying'ono yosalekeza nthawi zambiri imakhala yopitilira, kutalika kwake kumakhala 130 ~ 160mm, kutalika kwake kumakhala pafupifupi 6 ~ 12 metres, ndipo kulemera kwa billet limodzi ndi matani 1.5 ~ 3.Mizere yambiri yogubuduza imakonzedwa mosinthana mopingasa komanso moyimirira, kuti azitha kugubuduka mosadukiza pamzerewo.Malinga ndi kusiyanasiyana kwa ma billet ndi makulidwe azinthu zomalizidwa, pali 18, 20, 22, ndi 24 mphero zazing'ono, ndipo 18 ndizomwe zimayendera.Kugudubuza kwa bar kumatengera njira zatsopano monga ng'anjo yowotcha, kutsika kwamadzi othamanga kwambiri, kugudubuza kocheperako, komanso kugudubuzika kosatha.Kugudubuza movutikira ndi kugudubuza kwapakati kumapangidwa kuti zigwirizane ndi ma billets akulu ndikuwongolera kulondola.Kutsirizitsa mphero makamaka Kupititsa patsogolo kulondola ndi liwiro (mpaka 18m/s).Zomwe zimapangidwira nthawi zambiri zimakhala ф10-40mm, ndipo palinso ф6-32mm kapena ф12-50mm.Makalasi azitsulo opangidwa ndi otsika, apakati komanso apamwamba a carbon zitsulo ndi zitsulo zotsika kwambiri zomwe zimafunidwa kwambiri ndi msika;Kuthamanga kwakukulu ndi 18m / s.Kapangidwe kake ndi motere:
Ng'anjo yoyendera ng'anjo → chigayo chokhotakhota → chigayo chapakatikati → chigayo chomaliza → chipangizo chozizirira madzi → bedi lozizira → kumeta ubweya woziziritsa → chipangizo chowerengera chodziwikiratu → chowotchera → choyimitsira katundu.Kuwerengera kulemera kwake: m'mimba mwake kunja Х m'mimba mwake Х0.00617=kg/m.
